The author mentioned the following in the article:
The authors report a redox-neutral, catalytic C-C activation of cyclopropyl acetates to produce Si-containing five-membered heterocycles in a highly regio- and chemoselective fashion. The umpolung α-selective silylation leading to dioxasilolanes is opposed to contemporary β-selective C-C functionalization protocols of cyclopropanols. Lewis base activation of dioxasilolanes as α-silyl carbinol equivalent undergoes the unconventional [1,2]-Brook rearrangement to form tertiary alcs. Notably, mechanistic studies indicate that an electrophilic metal-π interaction harnessing highly fluorinated Tp(CF3)2Rh(nbd) catalyst permitted a low temperature C-C activation. To complete the study, the researchers used Methyl 3-methylbenzoate (cas: 99-36-5) .
Methyl 3-methylbenzoate (cas: 99-36-5) is a common ester. Esters are widespread in nature and are widely used in industry. Several billion kilograms of polyesters are produced industrially annually, important products being polyethylene terephthalate, acrylate esters, and cellulose acetate.COA of Formula: C9H10O2
